      • forJAVA

        public static SignatureAlgorithm forJAVA​(String javaName)
        For given signature algorithm and digest algorithm this function returns the Java form of the signature algorithm Signature Algorithms The algorithm names in this section can be specified when generating an instance of Signature. NONEwithRSA - The RSA signature algorithm which does not use a digesting algorithm (e.g. MD5/SHA1) before performing the RSA operation. For more information about the RSA Signature algorithms, please see PKCS1. MD2withRSA MD5withRSA - The MD2/MD5 with RSA Encryption signature algorithm which uses the MD2/MD5 digest algorithm and RSA to create and verify RSA digital signatures as defined in PKCS1. SHA1withRSA SHA256withRSA SHA384withRSA SHA512withRSA - The signature algorithm with SHA-* and the RSA encryption algorithm as defined in the OSI Interoperability Workshop, using the padding conventions described in PKCS1. NONEwithDSA - The Digital Signature Algorithm as defined in FIPS PUB 186-2. The data must be exactly 20 bytes in length. This algorithms is also known under the alias name of rawDSA. SHA1withDSA - The DSA with SHA-1 signature algorithm which uses the SHA-1 digest algorithm and DSA to create and verify DSA digital signatures as defined in FIPS PUB 186. NONEwithECDSA SHA1withECDSA SHA256withECDSA SHA384withECDSA SHA512withECDSA (ECDSA) - The ECDSA signature algorithms as defined in ANSI X9.62. Note:"ECDSA" is an ambiguous name for the "SHA1withECDSA" algorithm and should not be used. The formal name "SHA1withECDSA" should be used instead. <digest>with<encryption> - Use this to form a name for a signature algorithm with a particular message digest (such as MD2 or MD5) and algorithm (such as RSA or DSA), just as was done for the explicitly-defined standard names in this section (MD2withRSA, etc.). For the new signature schemes defined in PKCS1 v 2.0, for which the <digest>with<encryption> form is insufficient, <digest>with<encryption>and<mgf> can be used to form a name. Here, <mgf> should be replaced by a mask generation function such as MGF1. Example: MD5withRSAandMGF1.
        Parameters:
        javaName - the java name
        Returns:
        the corresponding SignatureAlgorithm
